Answer:

  285 centiliters

Step-by-step explanation:

Using the given conversion factor:

  1 quart = 0.95 L = 95 cL

  3 quarts = 3 × 95 cL = 285 cL

There are approximately 285 centiliters in 3 quarts.

__

Centi- is a prefix meaning 1/100th. So, 0.95 L (95 hundredths) is 95 cL.

Answer:

136

Step-by-step explanation:

Bc i took the flvs test and got it right

The triangle ΔXAC formed by the angle bisectors is an isosceles triangle

The measure of m∠CXA is the option;

136°

Reason:

The given parameters are;

ΔABC = An isosceles triangle

BF, AD, and CE = Angle bisectors, intersect at X

m∠BCA = 44°

m∠XCF = m∠XCD Angles formed by angle bisector CE

We have;

m∠BCA = 44° = m∠XCF + m∠XCD; by angle addition Postulate

∴ 44° = m∠XCF + m∠XCF; by substitution property of equality

44° = 2 × m∠XCF

m∠EAF = m∠XAF + m∠XAE

m∠XAF = m∠XAE;  Angles formed by angle bisector AD

∴ m∠EAF = m∠XAF + m∠XAF

m∠EAF = 2 × m∠XAF

m∠EAF  = 44°; by base angles of isosceles triangle

m∠CXA + m∠XCF + m∠XAF = 180° Angle sum property of a triangle

m∠CXA = 180° - (m∠XCF + m∠XAF )

Which gives;

m∠CXA = 180° - (22° + 22°) = 136°

Answer:

5

Step-by-step explanation:

on day 1 you had 20 pieces and each day you lose 2 pieces. so that means your equation is y=-2x+20. So x = number of days, and y = pieces of candy. Plug in 10 for y, minus 20 to both sides, divide by -2 to each side. Then your answer is 5.

Answer:

x = 150

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 6 , then

sum = 180° × 4 = 720°

Sum the given interior angles and equate to 720, that is

130 + 90 + 120 + 112 + 118 + x = 720, simplifying

570 + x = 720 ( subtract 570 from both sides )

x = 150

===============================================

Explanation:

Let's see if we can find a pattern where we divide powers of 3 over 30

In other words, let's see if we can find a pattern for (3^n)/30 where n is a natural number {1,2,3,4,...}

We only care about the remainders so ignore the quotients.

This is the pattern of remainders:

We see the pattern repeating again after we get to remainder 3 a second time. The pattern of remainders is {3, 9, 27, 21} which repeats forever.

The length of this cycle is 4. So what we do is divide the exponent by 4 to see what the remainder is. For instance, both 1 and 5 lead the same remainder when we divide by 4. This tells us 3^1 and 3^5 lead to the same remainder as shown in the pattern above.

Similarly, 3^2 and 3^6 lead to the same remainder. These items are spaced exactly four units apart, which is the length of the cycle.

For the exponent 2020, we get 2020/4 = 505 remainder 0

Having a remainder 0 is the same as having remainder 4, when dividing by 4.

So we'll be looking in the fourth slot of the cycle {3,9,27,21} to see the answer is 21.

Dividing 3^2020 over 30 leads to a remainder of 21.

Answer: x = 20

Step by step explanation:

Let's say that "___" = x to get rid of confusion when solving.

The new equation is 10% of x = 2.

Let's rewrite 10% as 10/100 and "of" as the multiplication sign.

10/100 * x = 2

Let's simplify 10/100 as 1/10 by dividing it by 10/10 which is one(there is no change in its value, it just makes our job easier.)

1/10 * x = 2

We can now multiply both sides by 10 to get x = 20.

Let's check: 1/10 * 20 = 2, so it is correct.

Answer:

I believe it is an acute triangle but im not 100% sure

Step-by-step explanation:

The triangle with sides 21 , 28 and 35 is a right angle triangle

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔABC

Now , the base of the triangle is BC = 21

The height of the triangle AB = 28

The hypotenuse of the triangle is AC = 35

And , for a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

Substituting the values in the equation , we get

35² = 21² + 28²

On simplifying the equation , we get

1225 = 441 + 784

1225 = 1225

Hence , the triangle is a right angle triangle

Answer:

p = 2

Step-by-step explanation:

Happy to help.

When we have numbers in parenthesis, we generally want to deal with those first. However, we can hit a rough patch when a variable is in there. Consider this:

2(3 + 4) = 2(7), or 14.

But, the two can also be distributed into both numbers in the parenthesis, like this:

2(3 + 4) = 2*3 + 2*4

That leaves us with the same answer—14! We can apply this to a variable, and that will help us figure out 9(p - 4), or the left side of your equation you presented.

9(p - 4) = -18

9*p - 9*4 = -18

9p - 36 = -18

Add 36 on both sides to isolate the variable (in this case, p)

9p = -18 + 36

You can also write it like this; 9p = 36 - 18

9p = 18

Divide 9 to isolate p

p = 2

So, we would get (p = 2). Make sure to practice a few more questions like these to really get the hang of it—you'll be using this a lot in the future!

Good luck!

The first one is the third root of 5^2. The denominator represents the root in which you're taking, in this case the third root, and the numerator represents the exponent that will be underneath the radical with the integer

The second one is the square root of 5. Anytime you see a 2 as the denominator in an exponent you're just taking the square root

The third one is the fifth root of 3^2, as explained by the first one

Answer:

3/28

Step-by-step explanation:

James read an equal number of pages of his book each night for 8 nights to prepare for his upcoming exam.

The total fraction of the book he read in 8 nights = 6/7

Hence,

8 nights = 6/7

1 night = x

Cross Multiply

8x = 6/7 × 1

x = 6/7 ÷ 8

x = 6/7 × 1/8

x = 3/28

Therefore, every night, the fraction of the book he has read is 3/28

Answer:

(a + 8)(a + 1)

Step-by-step explanation:

We know that the first term is squared, so we can put it out like this:

a * a

The third term has to be separated so that the sum of the two factors is the coefficient of the second term, 9.

8 = 4 * 2 (does 4 +/- 2 = 9? nope, we can't use that)

8 = 8 * 1 (does 8+/- 1 = 9? yes, when 8 + 1)

So the factor is a + 8 and a + 1.

Put this together and (a+8)(a+1)
